Split a task

On the task's Gantt bar, click the area of the bar on the date where you want the split to occur, and drag the second part of the bar to the date that you want work to begin again.

Note:

You can split a task multiple times.

To remove a split on a task, drag a portion of the Gantt bar so that it touches another portion.

If you identify nonworking time on a calendar to indicate a split, the nonworking time will not appear as a split task on the Gantt Chart view.

If your project has tasks that were already split, but you aren't sure why, your project may have been leveled while allowing splits to occur. On the Resource tab, in the Level group, click Leveling Options. In the Resource Leveling dialog box, select the Leveling can create splits in remaining work check box to allow splits as a result of leveling, or clear this check box to prevent splits during resource leveling.

Move one portion of a split task

Position the pointer over any portion of the split task other than the first portion. The cursor changes to a four-way arrow

Drag the taskbar left to start the portion earlier or drag it right to start it later.

Note:

If you drag the first portion of a split task, the entire task moves.

If you drag a portion of a split task and drop it directly next to another portion, it will be incorporated into the other split task portion.
